NOTES
G. REMOVING
DOOR
1. When removing the magnetron from the cavity or
wave guide, use aproper care sothatthedome
of the
magnetron dose not hit any adjacent parts of micro-
wave oven,
2. Make
sure that
the
contact
face of the
magnetron
gasket is free from any damage or deformation,
3, Adjust
the
position
of the
magnetron
properly,
so
that
it
correctly
sits
in
place
and the
magnetron
gasket is in contact
with the mounting
rim evenly.
4. While
holding
the
magnetron
under
this condition,
tighten
mounting
screws
or nuts with
your
fingers
temporarily y.
5. F uther tighten
the screws or nuts with a box wrench,
giving
one
or two
turns
to each of the screws (or
nuts) alternatingiy
so that the magnetron
is mounted
on to the bracket
uniformly.
6. After
replacing
the magnetron,
be sure to check
the
microwave
energy
leakage
with a leakage
detector
and
confirm
the
leakage
is
below
5 mW/cm2.
F.
REMOVING
FUSE
Remove
the 8A fuse with a screwdriver.
NOTES
–
When
replacing
the 8A fuse,
be sure
to use an
exact
repair
part
–
If the
8A
fuse
blows
immediately,
check
the
primary
interlock
switch,
the
relay
2
(on
the
control
circuit
board)
and
the
interlock
monitor
switch
according
to
"CHECKOUT
PROCEDURE
FOR
SWITCHES"
on
page
6. And
make
sure
to
check
the microwave
energy
leakage
according
to
"l.
ADJUSTMENT
PROCEDURES"
on
page
1,
when
the
primary
interlock
switch,
the
relay
2 or
the
interlock
monitor
siwtch
is
adjusted
or
replaced.
– If the
primary
interlock
switch,
the
relay
2 and
the
interlock
monitor
switch
operate
properly,
determine
which
of the
followings
is defective:
control
circuit
board,
blower
motor,
high
voltage
transformer
high
voltage
capacitor,
high
voltage
diode
or magnetron.
– If the high voltage
diode
is defective,
replace
not
only the high voltage
diode but also the fuse diode.
(1)
Remove 2 screws securing tha upper hinge,
(2)
Tilt the top of the door toward
you.
(3)
Lift UP the door to remove it.

NOTES
—
After
replacing
the door,
be sure to check that
the
primary
interlock
switch,
the
door
sensing
switch
and,
the
interlock
monitor
switch
operate
normallv.
(See page 1 )
–
After
replacing
the door,
check
for
microwave
energy leakage with a leakage detector.
Microwave
energy
leakage
must be below the limit
of 5 mW/cm2.
f-f. DISASSEMBLING
DOOR
(Figure 15)
(1)

(3)
Pull 2 plastic stopper of the right side.
Insert
a thin
flat-blade
screwdriver
between
the
choke dielectric
and the door
main
frame
and lift
up the choke dielectric
to release hooks one by one.
To remove
the plastic door panel,
insert a thin flat-
blade
screwdriver
between
the door
cover and the
door
main
frame
and detach
the door cover (with
plastic door panel).

NOTE
–
The choke dielectric
and door cover may be da-
maged
when
they are removed.
When reinstall ing[them,
rePlace them with new ones
if they are damaged.
–
After
installing
the door in place, check for mi-
crowave
energy leakage with a leakage detector.
Microwave
energy
leakage
must be below
the limit
of 5 mW/cm2.
